Application filed December 1.5, 1915. Serial No. 67,002.

To all whom it may concern Be it known that I, LEWIS E. a citizen of theUnited States, residing at Kane, in the county of McKean and State ofPennsylvania, have invented certain new and useful Improvements inBelt-Clamps; and I do hereby declare the following to be a full, clear,and exact description 0' the invention, such as will enable othersslrilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in belt clamps andthe principal object of the invention is to provide a device which isadapted for temporarilv Dn CAMP,

holding the end of belts while lacing while in use in the field.

Another object of the invention is to provide a quickly adjustable clampwhich may be easily adjusted to the ends of the belt and firmly hold thesame against accidental movement.

Still another object of the invention is to provide a clamp which isactuated by the throw of a single lever which controls the movement of acam by means of whichthe jaws of the clamp are moved into clamping iposition.

lVith these and other objects in view, the invention consists in thenovel combination and arrangement of parts which will be fully set tionand accompanying drawings, in which:

Figure 1 is a side elevation of a clamp constructed in accordance withthis invention.

Fi 2 is a vertical sectional view on line 2-2 of Fig. 1.

Fig. 3 is a detail perspective view of the clamp showing the cam andsupporting mechanism therefor removed, and

Fig. 4: is a fragmentary detail view on an enlarged scale partly insection, of the cam and supporting element.

Referring to the drawings the numeral 1 designates as an entirety themain jaw member of the device comprising the bottom bar 3 provided onits inner face with a plurality of teeth 3 formed-at opposite ends withthe bar 2 are the upturned arms t. which are slotted'as at 5 to providemember which will be more fully hereinafter described. A. suitable hingebarrel 6 is formed centrally of the upper end of each of the arms a and1s adaptedto form a support to the upper forth in the followingspecifica for the cam holding elements which will be.

more fully hereinafter described.

The cam holding elements above referred to comprise the arms 6 providedat their outer terminals with the hinge barrels 7 which are adapted toreceive the hinge pin 8 which extends through the hinge barrel 6 andholds the arms 6 firmly connected endsof the arms 4:. Formed centrallyof each pair of arms 6 are the circular plates 9 which are joined by anarcuate web 10,which conform to the curvature of the lower edge of eachof the plates 9. The web 10 is formed with acentra opening andsurrounding the opening is an externally screw threaded sleeve 11 onwhich the nut 12 is threaded. This sleeve is provided with a pair ofdiametrically opposed slits 13 and is adapted to form a guide for theplunger 14, the upper end of which bears against the cam 15 which ispivoted as at 16 near the upper edges of the plates 9 and has formedintegral therewith, the-lever 17 by means of which it is moved into itsoperative and inoperative position.

Cooperating the jaw memb with the jaw member 1 is er designatedgenerally by the numeral 18 comprising the body 19 having secured to itsunder side suitable spurs or pins 20 and formed at opposite ends of thebody 19 are the tongues 21 which are slidable in the slots 5. A suitablespring designated by the numeral 22 is secure to the upper side of thejaw member 18 in any suitable manner and comprises a bow 23 having theends of its arms bent so the they extend parallel and lie against theupper face of the jaw member 18 as at 24:. It will be apparent from theforegoing that in use the two ends of the belt are brought together andupon movi g the cam into the position shown in Fig. 1, 'it will be seenthat the plungerl l will be moved downwardly againstthe bow portion 23of the spring 22, thereby causing the jaw member 18 to move downwardlyin the direction of the jaw member 1 and firmly grip the ends of thebelt holding the same in place during its use in the fiel release thedevice the cam dotted line position shown in it will be seen that theplunger to move upwardly and the jaw member 18 will be released and freeto move in the direction of the cam thereby releasing the In order to isthrown into B 1g. 1 and will be free 7 .of the plunger to belt andallowing the device to be removed therefrom.

While in the foregoing there has been shown and described the preferredembodiment of this invention, it is to be understood that such changesmay be made in the combination and arrangement of parts as will fallwithin the spirit and scope of the appended claims.

Vhat is claimed is 2 l. A clamp comprising a stationary jaw memberprovided with arms at opposite ends, a movable jaw member slidablebespring on the upper side of the movable jaw member, a plunger forengaging the bowed portion of said. spring, a cam for engaging the upperend thereof against thespring to move the movable jaw member toward thestationary jaw member and sup 'iorting means for said cam hingedlyconnected to the arms of the stationary jaw member.

2. A belt clamp comprising a relatively stationary jaw member, armsformed integrally With and. rising vertically from the opposite ends ofthe stationary jaw' mem her, said arms having slots arranged cen- Gopiesof this patent may be obtained for five cents each, by

force the lower end the arms for hingedly trally therein, hinge barrelsformed on the upper edges of said arms, a movable jaw member locatedbetween the arms of said stationary member, said movable jaw providedwith tongues at opposite ends thereof, said tongues slidably mounted inthe slots of the arms of the stationary jaw member, which slots preventany lateral moven'ient of the tongues of the movable member withrelation to the stationary member, a bow spring arranged on the upperface of said movable member, a plunger for engaging the bowed portion ofthe spring, a cam operating against the upper end of the plunger forcingthe movable member toward the stationary jaw member, and sun portingmeans pivotally connected to the cam at one end and their opposite endshingedly secured to the hinge barrels on supporting the cam above themovable member.

In testimony whereof I presence of two witnesses.

LEW IS E. DE CAMP.
